i hv try using Visual Basic send a char"a" to my pic16f877a. but i try it many time still failed to do that. when i press a button in Vb was command the blue solei serial port status just ony show i had sent out data but the received keeping show in "0" bytes.. how can i solve it?

kl84 WROTE:I have to tell u that your question is too general. We need more well organized info in order to help...

Agreed with kl84, I totally don know where to seek for possible errors, too many. Assuming you are using the Bluetooth Starter Kit, connect to PIC and uses a PC to send data through another Bluetooth, right? Why don you connect the SKKCA to a computer to verify first. Is it the SKKCA cannot receive data or the PIC? Try verify the path and minimize the error scope.

Hi, trying to understand the problem here, help me on this. So you have connected the SKKCA to PIC through UART, and the SKKCA is connected to Bluetooth dongle on your computer wirelessly through Bluetooth link. You develop a program to send char to COM port. BlueSoleil show that you have send data out, but the PIC site show "0"?
